Maya Hotel Floating Pyramid Island in Caribbean Sea

"The $209 million Maya Hotel located south of Cancun, slated to open in 2010. This pyramid-shaped hotel will float in the crystal clear Caribbean waters with the help of a new composite material, normally used in the defense industry, which is billed as six times lighter and ten times stronger than steel."

As long as it could MOVE and get the hell away from hurricanes, and also not completely melt and give off tons of toxic fumes if there was a fire, it would be ok. Looks like it would be like being on a particularly spacious cruise ship.
